Intro

01 · THE EDITABLE AI GAME ENGINE

AI can make a game.
Can you keep changing it?

BYC Engine preserves more than the finished game. It keeps every generation step between your prompt and the playable result, so you can return, edit, and continue at any time.

TYPICAL AI GAME GENERATIONRESULT ONLY
PROMPT→BLACK BOX→3D GAME

AI produces the game, but the steps behind it are difficult to reopen and change.

BYC ENGINEEVERY STEP SAVED
Prompt→World→Logic→UI→Game

BYC saves every step as a Snapshot. Return to any point, make an edit, or branch into a new version.

Generation is only the beginning. BYC keeps the entire AI game-making process open and editable.

02 · FROM PROMPT TO PLAYER CONTROL

Create, save, and edit
in one continuous workflow.

Follow what AI generates, what BYC preserves, and where you take control.

03 · EVERY STEP, PRESERVED

Every Snapshot is
a place you can continue from.

The finished game is not the only thing that remains. Its creation history becomes a reusable structure for editing and experimentation.

04 · FREE TO USE

Use your existing coding subscriptions.
No separate API bill.

BrewYourCode can use the coding models you already pay for through Claude Code and Codex CLI. Connect them locally, keep your credentials on your machine, and generate without adding a separate API key or usage-based API bill.

Claude Code

Use a Claude Pro or Max subscription through the local Claude Code CLI.

  1. Install: npm install -g @anthropic-ai/claude-code
  2. Run claude once and sign in with your Claude account.
  3. In BrewYourCode, choose Option → AI keys → Claude CLI (subscription).

OpenAI Codex CLI

Use your ChatGPT subscription through the local Codex CLI.

  1. Install: npm install --global @openai/codex
  2. Run codex login and sign in with ChatGPT.
  3. In BrewYourCode, choose Option → AI keys → Codex CLI (subscription).

No API key is required for either subscription mode. Your subscription provider may apply its own plan limits; BrewYourCode does not charge a monthly fee.

05 · PROJECT DELIVERY

Run a project bundle on the web.

Export a project bundle from BrewYourCode, then run it on the web or in your own environment.

Get it

Download the authoring app

Create projects with the BrewYourCode desktop app for Windows or macOS. Connect Claude Code, Codex CLI, or your own API keys, then export a portable project bundle.

What it does

Local-first, your AI keys

Claude Code, OpenAI Codex, and Google Gemini calls go directly from your machine to the provider. Prompts and content do not pass through BrewYourCode servers, and your API keys are never uploaded.

Claude Code + OpenAI Codex support

Use Claude Code or OpenAI Codex with your own credentials. Open Option → AI keys to connect Claude Code, an OpenAI API key, or the local Codex CLI. See the setup guide.
